摘　　要：采用模拟酸雨浸泡实验,以红壤为研究对象,探讨了酸雨作用下红壤中铁铝形态的变化及其与土壤有机质的相关性。酸雨作用引起红壤酸化,促使红壤中铝铁形态发生变化;酸雨作用下,红壤中交换态、络合态铝铁含量有所减少,无定型铝铁含量有所增加,酸雨酸度越大,变化趋势越明显;酸雨促进土壤有机质的淋失,酸雨酸度越大,有机质淋失量越大;酸雨作用下红壤中铝铁形态与红壤有机质之间存在显著相关性。In this study,the simulated acid rain soaking experiments are carried out to investigate the form changes of iron and aluminum in red soil,and its correlations with soil organic matter.The results show that acid rain can cause the acidification of red soil,leading to the Fe/Al form change.Under the impact of the acid rain,the exchangeable Fe/Al and complex Fe/Al in red soil decrease,while the amorphous Fe/Al increases.The higher the acidity,the more obvious the change trend.Besides,acid rain can result in the leaching of soil organic matter.The higher the acidity,the greater the leaching amount.There is a significant correlation between the Fe/Al form and the organic matter in red soil.
